    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Any difference between years of manufacture?

I've got a GS400 (Frame number GS400 - 72977 and engine number GS400 ? 77872) in Australia that I'm trying to locate parts for it on various US websites. My registration claims the bike is a 1980 unit but I can't find any parts for 1980 GS400 only 1977-1979. The various shops in the US tell me they don't sell parts for international models but I think that's just because they are also unsure of the exact year of my bike.

Can anyone tell me the year of my engine from the engine number? Was there any engine changes between 1979 and 1980 or can I rest assured that if I get rings, gaskets, etc from either year it will fit?
 
Here in the USofA, our last 400 was in '78.

Other non-US owners have found success at a place in Europe, at csmnl.com.

The states only received the 2 valve per cylinder model. I suspect you have a 4 valve per cylinder model. Canada and Europe received the 4 valve model as well. That's all I have for you.
